Documents to gather
Bring any GIA or EGL report, valuation certificate, insurance paperwork, invoice, repair record, and clear photos. If the stone has a laser inscription, note it.
What not to do
Do not accept a pressure offer, hand over the ring without paperwork, or rely on a buyer who will not explain the valuation method. Avoid meeting unknown private buyers in unsafe settings.
Why Prodiam is a fit
